By Deborah M. Piroch, Human Life International - The Institute for Family Studies reports, “In general, men are more likely than women to cheat: 20% of men and 13% of women reported that they’ve had sex with someone other than their spouse while married.”… “A person’s political identity, family background, and religious activity are also related to whether or not they cheat. Overall, Democrats, adults who didn’t grow up in intact families, and those who rarely or never attend religious services are more likely than others to have cheated on their spouse.
